Hi Eric, I would love to work on this issue!

Hey @kane-chang that sounds good, thanks! It's been awhile since I've seen any of these links, and had this original idea, but that would be great. Maybe we could start with just the example from Robin Wieruch, since that would tend to scale well for a SPA. Thanks for volunteering!
